... the exposure to frac-fluids. This technique provides the measurement of Young’s modulus and hardness. In this study, 12 samples from the Permian basin with a wide range in Total Organic Carbon (TOC: 0–7 wt.%) and carbonate (5–87 wt.%) were selected. Each sample was divided into two companion specimens: one...

We used techniques like multi- linear regression, lasso regression, support vector regression, random forest...

..., and mudstones and chert facies for the Woodford. By combining high-resolution geochemical and geomechanical data, two distinct trends were evident for both units, and illustrate that variations in organic contents, mineralogy and relative hardness can be grouped by the two main rock types for each unit...

... mechanical properties and brittleness index (BI) versus Schmidt rebound hammer hardness were analyzed, and acceptable correlations were observed; hence, these relations can be used to estimate mechanical properties form hardness measurements within the basin. Stress dependent permeability and porosity...

... Abstract Outcrop and subsurface cores are sampled for a variety of low-cost rock analyses, including: Chemical (XRF) and mineralogical (XRF, XRD, petrography) composition and stratification, hardness (Leeb rebound hardness tester); microfabric, porosity and permeability (SEM); organic content...

... cores were also examined. The half cores demonstrated similar mineralogy and mechanical properties. Among all the 16 selected shales, their paired half cores showed an average difference of 3.22 ± 1.90 % in mineralogy and of 6.89 ± 8.45 % in hardness. The differences were substantially reduced compared...

... of spontaneous fluid imbibition (brine and dodecane) on Young's modulus and hardness in shale. The measurements were made using a nanoindenter on shale samples from the Marcellus and the Woodford plays. A key objective is to compare weakening effects of brine versus dodecane. It was found that irrespective...

Previous geomechanical studies on Eagle Ford Shale and Niobrara Formation have suggested a good correlation between rock hardness and unconfined compressive strength. In contrast to the traditional triaxial and acoustic...
